JOHN IVENN EN AND CHARLES HART, OF FRISCO, UTAH, ASSIGI ORS OF ONE-THIRD TO JOHN H. JOHNS, OF SAME PLACE.

ORE CONCENTRATOR.

SPECIFICATION forming part of Letters Patent No. 558,915, dated April 21, 1896.

Application filed September 19, 1895. $erial No. 563,003. (No model.)

To all whom it may concern:

Be it known that we, JOHN WENNEN and CHARLES HART, citizens of the United States, residing at Frisco, in the county of Beaver and Territory of Utah, have invented certain new and useful Improvements in Ore-Ooncentrators and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

This invention relates to certain new and useful improvements in ore-concentratorsg and it has for its objects, among others, to provide a simple and cheap device of this class for concentrating gold, silver, copper, lead, and other valuable ores by water, so as to bring the minerals from ten tons of ore to one ton of concentrates, or if the ore contains, say, a large quantity of copper or lead or any low-price metal it can be reduced from four to six to one, or if it only contains, say, a few ounces of gold or silver to the ton fifteen or twenty tons can be reduced to one, and so on.

The concentrator is of novel construction, whereby more satisfactory results are attained, and simple means are provided for rotating it.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specially defined by the appended claims.

The invention in this instance resides in the peculiarities of construction and the novel combination and arrangements of parts, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters and figures of reference marked thereon, form a part of this specification, and in which- Figure 1 is a top plan view of our improved concentrator with portions removed. Fig. .2 is a vertical section through the same on the line 00 a: of Fig. 1. Fig. 3 is a detail showing the openings in the center of the heads.

Like letters and figures of reference indicate like parts in all the views.

Referring now to the details of the drawings by letters and figures, A designates the supporting-framework, which may be of any desired material and of the required height.

B is the central shaft, which is mounted to h revolve in suitable bearings, being loosely stepped at its lower end in a socket B, as seen in Fig. 2. Motion is imparted to this shaft in the following manner.

0 is a horizontal shaft mounted in suitable bearings on the framework and carrying near its inner end a worm O,which meshes with a worm-wheel B on the upper end of the shaft B, as shown, while upon the outer end of the shaft 0 is abevel-pinion C ,Wl1lCl1 meshes with the bevel-pinion D on the vertical shaft D, mounted in suitable bearings and provided with a crank d, designed to be connected with any suitable source of power. (Not shown.) This constitutes a simple means for operating the concentrator and permits of the machine being set up in any desired position.

E is a cast-iron center fast on the shaft B and having provision for the reception and securing of the radial arms E, which may be secured thereto in any suitable manner and which extend to and are secured to and supported upon the outer ring E said arms being arranged at an inclination, as shown in Fig. 2.

E are supports or a ring secured to the radial arms between their ends, as shown, and secured to the same is the plank or platform F, which constitutes a smooth table extending from the point so to the point it, with a grade or incline toward the center.

G is the launder, and G the heads for bringing the water from said launder to the concentrator. The water that brings in the ore after it is crushed enters the launder at the point 1 and feeds the heads from the said point 1 to the point 2 through holes g in the center of the heads, which incline in opposite directions toward said holes, as seen best in Fig. 2, and the water is distributed by the buttons G and from these openings it goes onto the con centrator at the points x very slowly, so that the dirt will settle on the table or platform F and the water and the light dirt pass off therefrom into the launder H, which is arranged at this point concentric with the inner periphery of the said table, as shown. Then clear water is brought into the launder G at the points 3, and flows from these points to the points 4 and 5 and is distributed over the heads G from the point 4 to the point 5 the same as the pulp. This is for cleansing the ore that has settled on the table from the pulp, washing the waste off into the launder H, as will be readily understood.

I is a water-supply pipe for supplying water, by which the concentrates are washed into the launder H from as to a," and from this launder taken away to a tank or other receptacle and allowed to settle. The waste water is conducted away from the launderll by the trough or pipe J and the second-class matter by the pipe or conduit K. This latter material may be saved and worked again, if desired.

In order to assist the concentrates in being moved from the platform into the launder II, we employ a reciprocatory brush L, arranged to be moved over the said platform and actuated by connection with the crank of the shaft or rod D.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages. For instance, the power may be applied directly to the shaft 0 and motion given to the vertical shaft D through the medium of the bevel-pinions on the said shafts C and D. In fact, this latter way will be found preferable. \Vhen power is applied directly to the vertical shaft or rod D, it should be provided with a separate crank for the attachment of the rod that actuates the reciprocatory brush.

Upon reference to Fig. 2 the manner of connection and operation of the brush L will be more clearly understood. In this View the brush is shown as carried by the lower end of the arm L, which is pivotally mounted at its upper end, as at Z, while between its ends it is connected by rod or bar L with the crank d of the vertical shaft orrod D. The connection between the lower end of the rod L and the brush maybe of any suitable form of pivotal connection whereby the necessary movements may be given to the brush.

By the construction hereinbefore shown and described we provide a device by which more satisfactory results are attained, the proportion of ore saved being greater and the consequent waste less than by prior constructions. The reciprocatory device for assisting the ore in its movement down the platform is important, while the brush connected with the vertical rod serves an important function and by the peculiar arrangement thereof and its actuating means requires but minimum power for its actuation.

hat is claimed as new is 1. The combination with the rotatable platform and the heads, of a reciprocatorybrush mounted to move over said platform to and from the center radially, and carried bya rod pivotallyinounted at its upper end for assisting the ore in its movement down said platform, as set forth.

2. The combination with the main vertical shaft and the platform carried thereby, of the worm wheel 011 said shaft, the horizontal shaft, the worm thereon meshing with said worm-wheel, the bevel-pinion on said horizontal shaft, and the vertical shaft having a crank and a bevel-pinion meshing with the bevel-pinion on the horizontal shaft, and a reciprocatorybrush arranged to be moved over the platform radially to and from the center to assist the ore to the discharge at the center and operatively connected with said vertical shaft substantially as and for the purpose specified.

3. The combination with the vertical shaft and the inclined platform carried thereby, of the launder arranged concentric with the inner periphery of the platform, a water-pipe for washing the concentrates into said launder a worm-wheel on said shaft, a horizontal shaft carrying a worm meshing with said worm-wheel, a bevel-pinion 011 the horizontal shaft, a vertical rod having a crank and carrying a bevel-pinion, a reciprocatory brush arranged over said platform to be moved radially with relation to said platform and means connecting the same with said rod, substantially as and for the purpose specified.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
